S37.33 Laceration of urethra

Name of the Condition

• Laceration of urethra

Summary

This condition involves a tear or cut in the urethra, the tube that transports urine from the bladder to the outside of the body. Lacerations can range from partial to complete disruptions and may affect urinary function, requiring medical evaluation and intervention.

Causes

Urethral lacerations commonly result from external trauma, such as pelvic fractures, falls, or direct blows to the perineum. Penetrating injuries, including gunshot or stab wounds, may also damage the urethra. Iatrogenic causes, such as improper catheterization or surgical procedures in the pelvic region, can lead to injury.

Risk Factors

• Pelvic fractures, particularly those involving the pubic bone or pelvic ring, increase the risk of urethral laceration. High-impact activities, motor vehicle accidents, and contact sports are associated with higher rates of trauma. Males are more frequently affected due to anatomical differences.

Symptoms

• Blood at the urethral meatus (opening), difficulty or inability to urinate, pain during urination, swelling or bruising in the genital or pelvic area, and possible blood in the urine (hematuria). Severe cases may present with signs of shock or perineal hematoma.

Diagnosis

Diagnosis involves a physical examination to assess for swelling, bruising, or blood at the urethral meatus. Imaging studies, such as retrograde urethrography or CT scans, are used to evaluate the extent of the laceration. Urinalysis may detect blood or other abnormalities.

Treatment Options

• Treatment depends on the severity of the laceration and may include catheterization to restore urine flow, pain management, and surgical repair for significant damage. Antibiotics may be prescribed to prevent infection.

Prognosis and Follow-Up

Prognosis varies based on the extent of the injury and timely treatment. Minor lacerations may heal with conservative management, while severe cases may require long-term follow-up to monitor for complications like strictures or incontinence.

Complications

Potential complications include urethral stricture (narrowing), urinary incontinence, infection, or chronic pain. Severe injuries may lead to permanent urinary dysfunction.

Lifestyle & Prevention

• Avoid high-risk activities that increase trauma exposure. Use proper techniques during catheterization or pelvic procedures to minimize iatrogenic injury. Wear protective gear during contact sports or activities with pelvic injury risk.

When to Seek Professional Help

Seek immediate medical attention if you experience blood at the urethral meatus, inability to urinate, severe pelvic pain, or signs of shock (e.g., dizziness, rapid heartbeat) after trauma.

Tips for Medical Coders

Document the nature and extent of the laceration, including any associated trauma or iatrogenic causes, to support accurate coding. Ensure clinical details align with the specificity of S37.33 for laceration of the urethra.
